Computational Fluid Dynamics

Thermal and Fluid-dynamical Optimisation of Passengers Comfort in a Touring Bus Cabin

G. Petrone[1], G. Fichera[2], and M. Scionti[1]
[1]Bus-Engineering S.r.l., Catania, Italy
[2]Department of Industrial and Mechanical Engineering, University of Catania, Catania, Italy

Innovations in air-conditioning and other forms of cooling or ventilation can be viewed as technological solutions improving environmental conditions that are beneficial for human health, comfort and productivity. This study deals with a thermal and fluid-dynamics investigation of ... En savoir plus

Atmospheric Icing of Transmission Line Conductor Bundles

T. Wagner[1], and U. Peil[2]
[1]International Graduate School of Risk Management of Natural and Civilization Hazards on Buildings and Infrastructure, Braunschweig, Germany
[2]Institute of Steel Structures, Technical University Braunschweig, Braunschweig, Germany

Hazardous for the transmission lines is not only the static ice load, but also the aerodynamic instability of iced cables. It can lead to large amplitude oscillations at low frequencies. Also, twisting due to asymmetrical iced cables may increase the fatigue rate. In extreme events, ... En savoir plus

Increasing Heat Transfer in Microchannels with Surface Acoustic Waves

S. Berry[1]
[1]Massachusetts Institute of Technology: Lincoln Laboratory, Lexington, MA, USA

In this numerical study, surface acoustic waves (SAWs) are evaluated as a potential disruptive flow technology for enhancing heat transfer in microchannels. Using COMSOL Multiphysics® software, the physics governing acoustics, single-phase-fluid flow and heat transfer are coupled. The ... En savoir plus

Blood Flow Patterns in a Patient Specific Right Coronary Artery with Multiple Stenoses

B. Liu[1]
[1]Department of Mathematics, Monmouth University, West Long Branch, NJ, USA

Atherosclerotic lesions preferentially develop in certain regions like bifurcations, branches, and bends [1, 2]. A possible explanation for such a preferential localization of atherosclerosis is that the geometry of the vessel influences the blood flow pattern. It suggests that the ... En savoir plus

The Simulation of Electric Field Distribution in Electrospinning Process

Y. Zheng[1], B. Xin[2]
[1]Donghua University, Shanghai, China
[2]Shanghai University of Engineering Science, Shanghai, China

The electric field plays a very important role in the electrospinning process, which needs to be seriously considered in the electrospinning configuration developing. High voltage involved in electrospinning process leads to difficulty in measuring the electric field. Numerical ... En savoir plus

Study of Supercritical Coal Fired Power Plant Dynamic Responses for Grid Code Compliance

A. Gil-Garcia[1], I. Kings[1], B. Al-Duri[1]
[1]University of Birmingham, School of Chemical Engineering, Edgbaston, Birmingham, UK

In clean coal technologies, improving energy conversion efficiency is one of the most important directions. Compared to traditional subcritical power plants, pressure-increased supercritical power plants improve the plant energy efficiency from 35% up to 45%. This work presents a study ... En savoir plus

Near-Wall Dynamics of Microbubbles in an Acoustical Trap

L. Wright[1], G. Memoli[1], P. Jones[2], E. Stride[3]
[1]National Physical Laboratory, Teddington, UK
[2]University College London, London, UK
[3]University of Oxford, Oxford, UK

Understanding the interactions between microbubbles and surfaces is key to the successful deployment of microbubbles in a range of applications. Two important examples are their use as a drug delivery mechanism, and their potential use of acoustically-driven bubbles as microscale ... En savoir plus

Hydrodynamics of Lake Victoria: Vertically Integrated Flow Models in COMSOL Multiphysics® Software

S. Paul[1], R. Thunvik[1], D. D. Walakira[2], J. Mango[2], J. Oppelstrup[3], R. Wait[4]
[1]The Royal Institute of Technology, Stockholm, Sweden
[2]Makerere University, Kampala, Uganda
[3]COMSOL AB, Stockholm, Sweden
[4]Uppsala University, Uppsala, Sweden

Lake Victoria is the largest tropical lake in the world and is very important for environment and economy in East Africa. The hydrodynamic processes in the shallow (40-80 m deep) water system are unique due to its location at the equator which makes Coriolis effects noticeable also for ... En savoir plus

Numerical Investigation of Heat Transfer of Aluminum Metal Foam Subjected to Pulsating Flow

A. Bayomy[1], M. Z. Saghir[1]
[1]Ryerson University, Toronto, ON, Canada

The rapid development of electronic devices leads to more demand for efficient cooling techniques. Porous media represent a convincing passive cooling enhancer due to its large contact surface area to volume ratio and intense mixing of ﬂuid ﬂow. In the present work, numerical studies ...

Pore-Level Influence of Contact Angle on Fluid Displacements in Porous Media

H. Ali Akhlaghi Amiri[1]
[1]University of Stavanger, Stavanger, Norway

Wettability affects two-phase displacements in porous media by determining the microscopic distribution of fluids in pore spaces. The impact of wettability on transport properties at macro-scales has been widely addressed in literature; however a deeper understanding of wettability ... En savoir plus
